Karen S. Allen, of New Rochelle and Valhalla, passed away on August 24, 2020. Born March 7, 1940 in Lima, Ohio to Simon and Opal (Parlette) Allen, she studied at the University of Tulsa and received her Master’s degree in Social Work from St. Louis University. In addition to her career as a mental health social worker at Albert Einstein Hospital, Bronx, NY, she was an avid fan of opera singer, Kiri TeKanawa, and traveled the world to attend her performances. She was also active in many cultural groups in her New Rochelle community, and helped to co-found Tutti Bravi Productions, Inc., a not-for-profit organization dedicated to honoring the history of Westchester through theatrical productions. A published author of a self-help book for MS sufferers, she wrote the first production for the company, an opera highlighting the life of former New Rochelle singer, Ellabelle Davis. Her love of books and reading made her a dedicated supporter of the New Rochelle Public Library, where she devoted many hours as a volunteer in the local history section. She also volunteered at the Humane Society where she enjoyed many hours in the cat room. She loved being called “the crazy cat lady!” Friends lovingly remember her as an intrepid spirit — small in stature, but with a gigantic heart! She was pre-deceased by her siblings Neil Allen, Stan Allen and Arlene Humphrey, as well as her beloved cat, Kiri-Kiri. Surviving family members include nieces and nephews Mark Allen Humphrey (Phyllis) of King City, Missouri; MaryAnn Benz of Casselberry, Florida; Michelle Marks (Martin) of St. Joseph, Missouri; Debra Hoffman (Galen) and Sheryl Ashley (William) of Huntington, Indiana; Linda Riggle (Mark) of Carmel, Indiana; Neil James Allen of Findlay, Ohio; Eileen Lane (Rex) of Otsego, Michigan; and David Allen (Kathy) of Elyria, Ohio. She is also survived by 16 great-nieces and nephews. One great-nephew pre-deceased her. Interment will be private, with a memorial service to be scheduled at a later date. In lieu of flowers, memorial donations may be made to: The New Rochelle Public Library, Tutti Bravi Productions, the Humane Society of Westchester, or Multiple Sclerosis Foundation of Ft. Lauderdale, Florida.
